Quantum Fourier analysis for multivariate functions and applications to a class of Schrödinger-type partial differential equations

Paula García-Molina, Javier Rodríguez-Mediavilla, Juan José García-Ripoll

In this work, we develop a highly efficient representation of functions and differential operators based on Fourier analysis. Using this representation, we create a variational hyb…
